The points that are in the solution set of the given system of inequalities are (2, 0), (0, 2), and (0, 3).
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
To determine which point is in the solution set of the given system of inequalities, we need to check each point to see if it satisfies both inequalities.
A) (2, 0)
Plugging in the values of x=2 and y=0 into the inequalities, we get:
2+0 ≥ 2 which is true, and
4(2)+0 ≥ -1 which is true.
Therefore, point A (2, 0) is in the solution set of the given system of inequalities.
B) (0, 2)
Plugging in the values of x=0 and y=2 into the inequalities, we get:
0+2 ≥ 2 which is true, and
4(0)+2 ≥ -1 which is true.
Therefore, point B (0, 2) is in the solution set of the given system of inequalities.
C) (0, 3)
Plugging in the values of x=0 and y=3 into the inequalities, we get:
0+3 ≥ 2 which is true, and
4(0)+3 ≥ -1 which is true.
Therefore, point C (0, 3) is in the solution set of the given system of inequalities.
D) (0, -1)
Plugging in the values of x=0 and y=-1 into the inequalities, we get:
0+(-1) ≥ 2 which is false, and
4(0)+(-1) ≥ -1 which is false.
Therefore, point D (0, -1) is not in the solution set of the given system of inequalities.
Hence, the points that are in the solution set of the given system of inequalities are (2, 0), (0, 2), and (0, 3).

Find the shaded area. Use 3.14 as the approximate value of pi.
Answer:
164.73 cm²
Step-by-step explanation:
Area of the shaded area = area of semi-circle - area of the triangle
Area of the semi-circle:
Area = ½(πr²)
r = ½ of 34 = 17 cm
π = 3.14
Area = ½(3.14 × 17²)
Area = 453.73 cm²
Area of the triangle:
Area = ½*b*h
b = 34 cm
h = 17 cm
Area = ½ × 34 × 17
Area = 289 cm²
Area of the shaded area = 453.73 - 289 = 164.73 cm²

Step-by-step explanation:
Two less than three times a number is equal to 19. What is the number?
The best way to approach a word problem like this
is to break it down into pieces, so we can understand it fully.
In this problem, we have a number, which we don't know.
We can use any variable to represent it.
So let's use the variable n to represent it.
"Two less than three times a number" means 3n - 2.
A common mistake is for students to put 2 - 3n.
However, the word "less than" switches the order around.
So we have 3n - 2 = 19.
Solving from here, we add 2 to both sides to get 3n = 21.
Now divide both sides of the equation by 3 and we have n = 7.
So the number is 7.

C.
X = -5
Step-by-step explanation:
Find the measure of angle A.
Answer:
30 degrees
Step-by-step explanation:
Keep this in mind, ALL triangles must equal 180 degrees.
This is an acute triangle, hence one of the angles is 90 degrees. To find the other two angles, we must solve for x. Since we know the sum of all angles in this triangle must equal 180 degrees, we know for setting up our equation, all the angles should equal 180.
[tex]90 + (x+37) + (x+67) = 180\\[/tex]
Now solve for x by isolating x
[tex]2x + 194 = 180\\2x=-14\\x=-7[/tex]
Our x is -7, now that we know that the numerical value of x is -7, replace x with -7 for angle A.
-7 + 37 = 30
<A is 30 degrees.
Check your work
Plug in -7 where you see x.
[tex]90 + (x+37) + (x+67) = 180\\90 + (-7+37) + (-7+67) = 180\\90 + 30 + 60 = 180\\180 = 180[/tex]
Turns out this was a 30-60-90 triangle. ✅

Answer:
Part A: 14x + 2
Part B: CJ's order is $30, and Cameron's order is $58.

21.6 Computer use. A random sample of 197 12th-grade students from across the United States was surveyed, and it was observed that these students spent an average of 23.5 hours on the computer per week, with a standard deviation of 8.7 hours. If we plan to use these data to construct a 99% confident interval, the margin of error will be approximately (a) 0.07. (b) 0.62. (c) 1.6. (d) 8.7.
Answer:
(c) 1.6
Step-by-step explanation:
Calculation for what the margin of error will be approximately
First step is to calculate Total hours spent
Total hours spent = (197 * 23.5 hours)
Total hours spent =4,625 hours
Second step is to find the square root of the sample size
Sample size=√197
Sample size=14.04
Third step is to divide the Standard deviation of 8.7 hours by square root of sample size of 14.04
= 8.7 hours /14.04
= 0.6196
Fourth step is to use the Z table to find Z value at 99% confidence
Z value at 99% confidence = 2.58
Last step is to calculate the Margin of error
Margin of error = 0.6196 * 2.58
Margin of error = 1.59857
Margin of error= 1.6 (Approximately)
Therefore what the margin of error will be approximately is 1.6

What is the x -coordinate of the x-intercept of the function 2/3y=−6x+12?
Answer:
y=9x+18
Step-by-step explanation:
to get 9, use the rise over run way. Using that, I got 9/1, which is equivalent to 9. Then you MUST add x after, so then you get 9x. The last number is always the y intercept, or where the line meets the vertical line. That was 18.

Find the volume of a region bounded by the functions y = 2x + 6, the y-axis, and the x-axis as it revolves
around the x-axis.
GRAPH !
V=
units3
(round to the nearest tenth)
The bounded region in question is a triangle in the second quadrant. The line y = 2x + 6 has intercepts (0, 6) and (-3, 0), so revolving the triangle about the x-axis forms a cone with height 3 and whose circular base has radius 6. Its volume would then π/3 • 6² • 3 = 36π ≈ 113.1 units³.
But you're probably supposed to use calculus. Using the disk method, the integral for the volume is
[tex]\displaystyle V=\pi\int_{-3}^0 (2x+6)^2\,\mathrm dx[/tex]
[tex]\displaystyle V=\pi\int_{-3}^0(4x^2+24x+36)\,\mathrm dx[/tex]
[tex]V=\pi\left(\dfrac43x^3+12x^2+36x\right)\bigg|_{-3}^0=\boxed{36\pi}[/tex]
as expected.
